RIFLE WITH PISTOL BREECH MECHANISM.

Application filed December 30, 1924. Serial No. 758,928.

which is similar to that of an automatically loading pistol. The rifleaccording to the invention presents the advantage 1n comparlson with themagazine rifles of known type, that the breech block and theentire'loading mechanism can be easily removed and that it can be made readyfor use as automatic pistol after a short barrel has been mounted on thesame. If the rifle is a re peater it is important that the pistol breechblock be mounted in the rifle without friction but nevertheless in astable manner and that it be brought back without friction and bymechanical transmission after the shot has been fired. These twoconditions are ful- In order rifle be unfavorably influenced by thepistol inserted in the rifle it is necessary to adapt the pistol triggerto the rifle trigger. At this occasion it is of advantage that thesafety device of the pistol is transferred directly to the outer side ofthe rifle so that a good outer appearance of the rifle is ensured aswell as an easy handling of the safety device.

An embodiment of the invention is shown, by way of example on theaccompanying drawings, in which Fig. 1 shows the improved rifle in sideelevation.

W1th the rifle barrel 1 the guide sleeve 2 is rigidly connected (Fig.2). In this guide sleeve 2 the breech block 4 with the handle 3 isslidably mounted. The butt 5 and the stock 6 are made in one piece. Inthe upper surface of the butt neck the tail 7 of the barrel is embeddedand in the lower surface On the lower surface of the rear part of thebarrel a T-bar 12 is formed (Fig. 3). The pistol breech block 13 and thepistol handle 14 are indicated in Fig. 1 by dash lines. The front partof the pistol handle 14 has a groove 16 of T-shaped cross section intowhich projects the spring-controlled holder 15 for the barrel. Thepistol mechanism is mounted in the barrel in the following manner:

The breech 4 open at the lower end is inserted into the guide sleeve 2of the rifle barrel 1 from the rear, whereupon the pistol handle 14' andthe breech block 13 are inserted into thebreech 4 open at the lower endand pushed forward so that the T-shaped groove 16 of the pistol handleengages over the T-bar12-of the barrel 1. The springcontrolled barrelholder 15 engages with a.

notch in said T-shaped bar 12. The rifle barrel is now rigidly connectedwith the pistol mechanism. A rearwardly inclined stud 17 of the guidesleeve 2 en ages with a corresponding hole in the tail? of the barrel sothat the pistol mechanism is also securely connected with the butt. Inthe stock 6 a vertical bolt 18 is located which has at its upper end abayonet joint 19 and at the lower end a hand lever 20. When the handlever 20 is rotated 90 the nose of the bayonet joint 19 engages with acorresponding recess of the barrel so that the bayonet j oint is closed.The rifle barrel, the pistol breech mechanism and the stock are nowsecurely connected with one another.

In order to use the breech mechanism 13 and the repeating mechanism 14as automatic pistol the connection with the rifle is loosened and ashort barrel, having a T- bar 12 on the lower surface, is inserted intothat when the trigger into two parts, the part4" of the same can berotated by means of the handle 3 in order to open the breech, the frontpart 4' remaining in the same position over the pistol breech block 13independently of the rotating movement of the rear part 4"; The backmovement of the breech for loading and unloading is done in the usualmanner.

The transfer mechanism of the trigger is mounted in the tail 7 of thebarrel. It consists essentially of the trigger rod 25, the angle lever26, the catch bolt 27 and the trigger 28 of the rifle having a guide pin29.. The trigger rod is bent and terminates as.

a hook 30 standing in front of the trigger.

31 of the pistol. The trigger rod 25 has a fork-shaped downwardlydirected arm 32 with which engages the uide pin 29 of the trigger 28.The angle ever 26 is fixed in the barrel tail 7 by means of a bolt 33.The, trigger rod 25 is controlled by the pressure of the catch bolt 27and fixed in the barrel tail 7 by means of a bolt 34 engaging with anoblong hole 35 of the trigger rod- 25 so that this trigger rod can movebackward when ashot is beln'g fired.

It is of special importance that the hook- -shaped end 30 of the triggerrod 25 grips the pistol trigger 31 only when the breech handle 3 hasbeen completely pressed into its seat so that no shot can be fired whenthe breech block of the barrel is not entirely closed. This is ensuredby the following operation In the lower part of the breeeh 4 a notch36is arranged with which engages the long; 7

er arm 37 of the angle lever 26. In Fig: 8 the breech handle 3 is shownin raised posi tion so that the breech mechanism of the rifle is notcompletely closed. At this state the hook 30 of the trigger rod 25 isstill at some distance from the pistol trigger 31 so 28 of the barrel isbeing pulled the book 30 would merely move along the pistol trigger.When however the breech handle3 iscompletely lowered, the straight faceof thenotch 36 acts upon the.

long lever arm 37 so that-the short arm 38 of the angle lever exerts apressuraupon' the trigger rod 25 so that its hook-shaped end I ger 31.The rifle is now in 30 is brought in c'ontact'with'the proper positionfor'firing a shot.

The pistol stop 39 acts for instance in the commonl used manner by meansof a shaft and of f0 dable wings. The rifle stop 40 consists also of awing 41.

pistol trig- The operation is as follows On the inner surface of therifle stock 5 a, spoon-shaped element 42 adapted to fit over the-stopwings of the pistol is arranged which is securely connected with thewing 40 of the barrel stop by means of a square head- 43 and by means ofa screw 44. The barrel stop and the pistol stop are situated in onestraight line. By the spoonshaped element 42 the movement of the barrelstop is directly transmitted to the pist'ol stop.
